IMPROVEMENT IN LAM P-BURNERS.

Specification forming part of Letters Patent No. 220,253, dated October7, 1879; application filed July 1, 1878.

To all whom it may concern:

Be it known that I, REUBEN B. PAINE, of Knowlesville, in the county ofOrleans and State of New York, have invented certain new and usefulImprovements in Lamp-Burners; and I do hereby declare that the followingis a full, clear, and exact description thereof.

My invention is a burner constructed, as de scribed hereinafter, toinsure the upward flow of currents of .air on opposite sides of theflame, spreading and maintaining the steadiness of the latter withoutliability of the airopenings becoming clogged up.

In the drawings, forming part of this specification, Fig. l is a sideview of the improved burner; Fig. 2, a section, and Fig. 3 a plan.

The burner consists of the metal case G, threaded to fit the lampsocket,the wick-tube T, and wick'raisin g pinions 11 arranged between rhetop hand bottom h of the case. The wicktube extends a short distance abovethe top of the case, and in said top, at opposite sides of the tube, aretwo narrow slots or openings, 12 I), nearly equaling in length the widthof the wick-tube, and in the rim of the casing are air-openings a c. Theair passing into the openings at 0 will take up the vapor which escapesfrom the slits in the tube T, through which the wick raising wheelspass, and, charged with these vapors, will rise in parallel streamsthrough the slots 12 and increase the combustion in the flame, and willtend to spread the latter,. and impart increased steadiness thereto.

I am aware that parallel tubes have been used in connection with a domehaving a flat top, with a central oblong opening longer than the breadthof the tubes.

I am also aware that side openings have been used in connection withwick-tubes projectin g to a considerable extent above the top of i theburner. rents to disturb those passing up through the side openings. Bymaking the tube extend only about its own thickness above the top thelodgment of particle's in the side openings is prevented, while the sidecurrents meet the flame before they can be deflected. Such constructionis objectionable, as the air passes up at the edges of the tubes,thereby disturbing the efiect of the side currents.

In my improved burner the lodging of any particles on the end of thewiclctube which projects above the openings will not clog the latter.There are no currents at the ends to diminish the Width of the flame,nor is there any conflict with the upward flow and lateral spread of thecurrents through the openings b.

I claim- The combination, in ano-chimney burner, of the case 0, having aflat imperforate top and peripheral openings, a wick-tube extendingthrough, and less than its own thickness, above said top, and parallelslots in the top, at the sides, and extending nearly to the ends of thetube, as and for the purpose set forth.
